session in

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error

error in contains an error

If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

size of instrument driver revision

Maximum size of the instrument driver revision output string, which must be set to a minimum of 2,048.

size of firmware revision

Maximum size of the firmware revision output string, which must be set to a minimum of 2,048.

session out

Reference to your instrument session to wire to the next node.

error out

Error information.

The node produces this output according to standard error behavior.

instrument driver revision

NI-FGEN software revision numbers in the form of a string.

firmware revision

Instrument firmware revision numbers in the form of a string. Not all instruments have firmware information available.
